Summary: In this study, we identified 104 NAC genes in tea plants and characterized one gene, CsNAC28, which was constitutively expressed and highly responsive to abscisic acid (ABA) treatment and drought stress. Biochemical and genetic approaches revealed that CsNAC28 functions downstream of CsABF2, a key regulator in the ABA pathway. Overexpression of CsNAC28 in Arabidopsis improved dehydration tolerance by reducing reactive oxygen species (ROS) accumulation. Our findings provide a foundation for understanding the molecular mechanism of drought responsiveness mediated by CsNAC in tea plants.

Summary: In this study, the cloning and characterization of a gene encoding a typical cotton NAC transcription factor, GhNAC2-A06, was reported. It was found that the expression of GhNAC2-A06 was induced by PEG treatment, drought stress, and ABA treatment. Using the virus-induced gene silencing method, the function of GhNAC2-A06 was investigated and it was discovered that GhNAC2-A06 plays a role in the reaction of cotton to drought stress by affecting the expression of genes related to drought stress. These findings provide a theoretical foundation for further research on the biological function and regulatory mechanisms of GhNAC2-A06.

Summary: Priming plants to mild elevated temperature improves their tolerance to high-temperature stress later, and this tolerance is maintained for an extended period of time, known as thermomemory. NAC transcription factors ATAF1 and ANAC055 play a core role in thermomemory, with ATAF1 negatively regulating thermomemory and ANAC055 potentially co-regulating it.

Summary: This study systematically characterized all NAC genes in Nelumbo nucifera and investigated their response mechanisms to salt stress. The results showed that NAC genes are responsive to biotic and abiotic stresses, light, low temperature, and plant hormones, and have tissue expression specificity. Three NAC proteins induced by NaCl and ABA were found to have transcriptional activation capabilities. The co-expression network analysis suggested that NAC proteins may form complexes with other proteins to function together.

Summary: Recent investigations have shown that SMAX1 and SMXL2 act as negative regulators of karrikin and strigolactone signaling during plant growth and development in Arabidopsis thaliana. However, their functions in drought resistance and related mechanisms are not well understood. This study found that the smax1 smxl2 double-mutant plants exhibited enhanced drought resistance and reduced leaf water loss compared to wild-type plants. Transcriptome analysis revealed that the cuticle formation mechanism was involved in the drought resistance of the mutant plants. Additionally, the mutant plants showed increased sensitivity to abscisic acid and higher reactive oxygen species detoxification capacity, as well as longer root hairs and a higher root-to-shoot ratio, indicating an improved water absorption capacity. These findings suggest that SMAX1 and SMXL2 negatively regulate drought resistance and disrupting these signaling-related genes may offer a potential strategy to enhance crop drought resistance.

Summary: This study aimed to identify key NO3- and/or Pi starvation-responsive metabolic pathways in chickpea and found significant differences in metabolic adaptation under single and double nutrient deficiencies. The simultaneous deficiency of NO3- and Pi generated unique metabolic changes that couldn't simply be explained by the combined deficiencies of the two nutrients.

Summary: High-yield crop varieties are highly sought after due to the increasing human population. The regulation of yield traits involves complex interactions of molecular and genetic factors controlled by various quantitative trait loci (QTLs). Recent studies have identified and characterized yield-associated QTLs, highlighting the central role of phytohormones in controlling plant yield. Different groups of phytohormones often work together to determine yield attributes, and understanding this interaction can facilitate the improvement of crop yield through the manipulation of a single gene or QTL(s). In this review, we discuss important findings regarding the roles of auxin, brassinosteroid, and cytokinin, and how a single gene or QTL can regulate cross talk among multiple phytohormones to determine yield traits.

Summary: Sclerotinia sclerotiorum is a fungus with a wide range of hosts that causes significant yield losses in various plant species worldwide. Its life cycle involves either basal infection or aerial infection, and it colonizes aging tissues before entering a saprophytic stage. The release of certain enzymes, acids, and proteins are crucial for its pathogenesis. Although the molecular basis of S. sclerotiorum pathogenesis is still unclear, previous genome sequencing has provided valuable insights into its growth, development, and virulence. This review focuses on the genetic and genomic aspects of S. sclerotiorum to summarize the current knowledge of its parasitic processes.
